The aim of the invention is to permanently and preventively display the complete transmission and service costs of internet, online and telecommunication services that are offered by corresponding service providers (telecommunications internet and/or data service provider T/DSP) during use of said services. To this end, the costs are recorded and calculated by the T/DSP and are then transmitted to the user. The T/DSP is linked with the data banks of the companies by means of automatic data exchange so as to detect all relevant costs, such as the telecommunication transmission costs, own link-oriented or volume-oriented costs as well as the costs for using services and optionally costs for service offers of third parties that market their services to the user via the T/DSP. These relevant costs for the respective connection are recorded and stored in said data banks. The T/DSP relevant costs are automatically transmitted from the above-mentioned data banks during a projected connection (session). They are transmitted upon an automatic inquiry by the T/DSP or on the basis of the limited access authorization of the T/DSP to the corresponding data.
